Drywall is a composite material sold in the form of sheets. Sometimes this material is called "dry plaster." At the heart of such a sheet is gypsum, and the outer layer is lined with cardboard. Often, components are added to the gypsum base to help “specialize” the sheet, giving it additional properties, thereby expanding the range of their application. As a result, not only standard drywall sheets are produced, but also fireproof, as well as waterproof sheets (GKL, GKLO or GKLV). The cardboard layer of such a sheet performs two very useful functions, acting as a reinforcing frame and a good foundation that can be finished with almost any material: wallpaper, paint, plaster, ceramic tile, etc. If you are installing gypsum board constructions with your own hands, you will need a spatula and high-quality screwdriver.
Fire-resistant drywall sheets have found their application in communication shafts, various air ducts, etc. Water-resistant drywall, which contains special substances that destroy fungi, has found its application in the decoration of bathrooms, bathrooms and kitchens. As a result, drywall sheets are both solid and flexible, giving good sound insulation and thermal insulation, while it is environmentally friendly, since it does not contain any harmful toxins. It is worth noting that many gypsum plasterboard constructions are made of it with your own hands quite simply, including aligning the walls yourself, and you can easily make a partition or arch of gypsum plasterboard with your own hands.
Mounting options.
There are several options for how to work with drywall with your own hands, using it to decorate or arrange walls, partitions or arches. By learning how to install drywall constructions with your own hands, you can mount any of the structures, whether it be a partition, ceiling, wall or arch made of drywall with your own hands.
You can stick sheets on the base wall. It is also possible to clad brick, concrete and other walls using a metal profile, or to make a partition or arch entirely from drywall.
As a rule, a profile or metal frame is created, but the use of wooden beams is also acceptable. The width of the created frame can vary from 50 to 100mm. It is advisable to lay soundproof materials under the guide profiles .
Alignment of walls on a metal frame
the frame for drywall systems is mounted on the wall according to standard technology. Creating wall-mounted drywall constructions with your own hands is much easier than installing a ceiling, so such work with drywalls with your own hands is doable even by an inexperienced person. Work begins with determining the level of the future surface of the wall. Next, intermediate profiles are fixed along its perimeter, and then proceed to the installation of supporting vertical profiles.
they should all be in the same plane. Achieve this result by pulling the cord in several rows between the extreme profiles. Alignment of the frame is performed on it. It is important to know that cruciform joints are not allowed when fixing gypsum plasterboard sheets. The final stage is the processing of joints and grouting of the fastening points with screws, and it is also desirable to prime the entire surface of the wall.
Alignment of walls with adhesive mixtures.
Work is performed when the wall deviations are not 30 mm. On the back side, in the center of the sheet and the perimeter indented from the edge of 50 mm, an adhesive mixture is applied with an adhesive roller. The sheet is attached to the wall, carefully verified in all directions. Having installed the sheets, we close up all the joints between them.
Arches can be mounted both in the doorway and in a brick or plasterboard wall. Installation technology will be different. One of the options for arched ceiling is as follows:
Two sheets of drywall are cut to the width of the opening, and then, using a jigsaw, blanks of the arch are cut along the previously outlined contours. Then both workpieces must be fixed on the installed frame so that the circles coincide.
For slopes, we prepare a strip of drywall, drill it, wet it, let it get wet, and screw it onto the inner surface of our arch onto the screws. The structures need to dry, after which we fasten the vertical slopes to the drywall frame, putty all the joints and grind the surface of the arch.
